Fix server error when editing a note to "+1" or "-1"

### Summary

If a user edits a comment with "+1" or "-1" in the beginning, the POST returns an Internal Server error. (issue #1151). This merge request resolves that error.

### Steps to reproduce

1. Comment on an issue with "Test comment".
2. Edit the issue.
3. Write "+1" and click "Save Comment".

### Expected behavior

The edited note should be saved and refreshed. Any previous upvotes/downvotes from the user should contain a strikethrough.

### Observed behavior

Internal Error

### Fix

It turns out no tests were present for the "Edit Issue" functionality. I added spinach tests to exercise this and reproduced the error.

Most of the routes in `notes_controller.rb` appear to render all notes for the given discussion. `_form.html.haml` needs the full list of notes commented by the user to add strikethroughs for older upvotes/downvotes. However, only the `index` route appeared to obtain this information. The fix is to add a `before_filter` to obtain all the user's notes beforehand, except in the delete case where this information is not needed.

Things to watch: `NotesFinder` needs `target_type` and `target_id` to determine what to do. I'm not sure if there is a conscious effort to phase these keywords out in favor of `noteable_type` and `noteable_id`.

Don't leak information about private project existence via Git-over-SSH/HTTP.

Fixes #2040 and https://gitlab.com/gitlab-org/gitlab-ce/issues/343.

Both `Grack::Auth` (used by Git-over-HTTP) and `Api::Internal /allowed` (used by gitlab-shell/Git-over-SSH) now return a generic "Not Found" error when the project exists but the user doesn't have access to it.

Render go-import meta tag for private repos.

The previously solution (626f5bab) required a change to nginx config and broke visits from Googlebot and other clients including "go" in their user agent.

Don't show Unassigned in user select when searching.

Fixes #2056.

When a search term is present, the Unassigned item isn't rendered, so the highlighted item is the first search result and hitting Enter works as expected.

Fix import check for case sensetive namespaces

Count commits in branches as well in the commit calendar

This MR fixes a small bug in the commit calendar.
Currently only commits that are in the master branch are counted.
With this change, commits in other branches are included as well.

Fix merge request URL passed to Webhooks

If you look at the data structure passed to Webhooks, you will see:

`"url"=>nil`

I don't think any of the Webhooks or services are using this yet, so right now nothing so far depends upon this value being correct.
